To all 107mm 'it may concern.'

Be it lmownthat I, JOHN B. SPERRY, a citizen of the United States, residing at Aurora, in thc county of Kane and State of Illinois, have invented certain new and useful Improvements in Deep-Tell Pumps, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to deep well pumps of the reciprocating type, and it has for its principal object the provision of a form and arrangement of parts by which the amount of water pumped may be made as great as is practicable, all of the lifting of the water being accomplished by the upstroke -of the plunger rather than by the down stroke. As will be readily understood, when pressure is applied to a long line of pump rods c, for forcing a plunger downward in the bottom of a well there is a marked tendency of the pump rods to buckle, causing an undue amount of friction in the operation of the pump and very often unduly increasing the It is important in many cases, however, that a maximum amount of water be pumped from a well, inasmuch as the sinking of a deep well in many localities involves a very heavy eX- pense. It is one of the objects of my invention to provide a construction involving the use of two cylinders, in each of which cylinders are mounted three plungers adapted to be operated by three pump rods respectively, the three pump rods being reciprocated in 120O phase relation relative to each other whereby at any given time one or another of the three plungers in each cylinder ns being moved through that portion of its stroke with approximately the greatest efficiency. By this means, yas will be readily understood, the column of water rising through each of the cylinders will be kept moving upward with approximate uniformity, thus increasing materially the efficiency of the operation of the pump as compared to that of'pumps in which the rise of the water through the cylinder is not so steady. It is another one of the objects of my invention to improve pumping apparatus of this general type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects vare illustrated 'in the accompanying drawings and are hereinafter specifically described.

`That which Iv believe to be new and desire to cover-by this application is set forth in the claims.

In the drawings Figure l is alongitudinal vertical section Vof theupperportion of pumping mechanism located at the bottom of a well, involving thel use of three plungers in each of the two cylinders provided; n

Fig. 2 is a central vertical section through a portion of the pumping apparatus at the bottom of the well, being a continuation downward of the view shown in Fig. l;

Fig. 3 is a central vertical section through a portion of the pumping apparatus at the bottom ofthe well, being a continuation downward of the view' show n in Fig. 2;

Fig. it is a central vertical section through the lower portion ofy thepumping mechanism at the bottom ofthe well, being a continuation downward of the view shown in Fig. 3;

Fig. lla' is a diagrammatic view showing one form of means for reciprocating the plunger rods in timed relation; and- Figs. 5 to l2 are horizontal vertical sections through the pumping apparatus, being taken on the Correspondingl'y-numbered section lines of Figs. 1 to ft. j

The pump rods of myvimproved pump are preferably operated by such a mechanism as that shown by the application of Matthew T. Chapman, for patent on pumping machinery, Serial No. 11,205, filed March l, 1915, but they may be operated by any other suitable apparatus.

Referring tothe several. figures, in which corresponding parts are indicated by the same reference characters, indicates a well tube extending down into a well, through which water or otherl fluid being pumpedis adapted to be forced to the surface. Extending down inside of the well tube'25 is a tubular pump rod 26, working inside ofwhich is a second tubular pump rod 27,'having a third pump rod 28 eX- tending down therein. The lower end of the v'well tube 25 hasy attached to it by means of a screw-threaded coupling 29 a tube or pipe 30, to the lower end of which there is connected by means of screw-threads a coupling device 31. The coupling device 31 has connected to its lower end two pipe sections 32 and 33, the pipe 33 being located inside of the pipe 32 and being spaced from the walls thereof. As shown in Fig. 2, the coupling 31 provides a tapering seat for a closure member 34 which serves to close the upper end of the pipe 33 except for the central vertical passage therethrough as hereinaii'ter described, the closure member 34 and the coupling 31 being also provided with registering annular openings therethrough by which the lower end of the pipe 30 communicates with the upper end of the pipe 32. The pipe 33 serves as the lower one of the two cylinders provided in my improved pumping apparatus, having mounted therein plungers 35, 36 and 37, connected as hereinafter described with the pump rods 26, 27 and 28, respectively. The pipe 30 and another pipe 38, mounted inside of the pipes 30 and 25 as hereinafter described, and connected at its upper end with the pump rod 26, together serve as the upper one of the two cylinders provided. Plungers 39, 40 and 41 are adapted to be reciprocated in the cylinder 30-38 by the plunger rods 262728, respectively, as hereinafter described.

As is shown in Figs. 1 and 6, the pump rod 28 has mounted upon its lower end a coupling device 42 by which a cross-head or spider 43 is iXedly secured to said pump rod, the said cross-head 43 having secured to it and depending therefrom a centrally-positioned rod 44 and a hollow pump rod section 45. As is shown in Fig. 4, the plunger 37 is mounted by means of screw-threads directly upon the lower end of the rod 44, said plunger being provided with a suitable packing 46 for engagement with the inner face of the pipe 32 and being provided with a valve 47 of any suitable type adapted to open upwardly. The plunger 41 is connected to the lower end of the pump rod section 45 by means of a coupling 48, of any suitable type, providing a suitable recess for packing 49 about a pump rod section 50 which is connected with the pump rod 27, as hereinafter described. rlhe plunger 41 is provided with an upwardly opening valve 51 of any suitable type and with packing 52 engaging the inner face of the pipe 38. The lower end of the tubular pump rod 27 is connected by means of screw-threads with a cross-head 53 which is rigidly connected by means of three pins or bolts 54 with a cross-head 55 mounted upon the upper end of the tubular pump rod section 50 by means of a coupling sleeve 56 which is joined to the cross-head 55 by means of webs 57. The plunger 40 is mountedxby means of screw-threads upon the lower end of the tubular pump rod section 50, serving also as a connection for a tubular pump rod section 58 to the pump rod section 50. The plunger 40 is provided with an upwardly-opening valve 59 of any suitable type and is provided with suitable packing 60 bearing against the inner face of the pipe 38. v Mounted upon the lower end of the tu bular pump rod section 58 is a Vcoupling member 61, to the lower end of which is connected a smaller tubular pump rod section 62, the coupling 61 being so arranged as to leave open the lower end of the tubular section 58. The plunger 36 is mounted directly upon the lower end of the tubular section 62 by means of a coupling 63, suitable packing 64 being provided between the plunger 36 and the pump rod section 44, and packing 65 being provided between the plunger 36 and the inner face of the pipe 33. The plunger 36 is provided with an upwardly-opening valve 66 of any approved type.

The upper end ot the pipe 38 is joined to the lower end of the tubular pump rod 26 by means of screw-threaded sleeves 6768 joined by radially-extending webs 69. As before described, the pipe 38 serves as a cylinder member for the plungers 40 and 41, but it also serves as a pump rod section for the plunger 39 which is mounted in its lower end by means of screw-threads. T he plunger v 39 is provided with packing 70 adapted to bear upon the inner face of the cylinder member 30, and the plunger is also provided with an upwardly-opening valve 71 of any suitable type. A pump rod section 72 is secured by means of screw-threads to the plunger 39 and extends downward therefrom, a packing 73 being secured in. the plunger 39 bearing upon the pump rod sec` tion 58 serving to close the upper end of the pump rod section 72 about the pump rod section 58. As is shown at the bottom ot Fig. 2, the closure member 34 is provided with a packing 74about the pump rod section 72. As is shown at the top of Fig. 3, a coupling member 75 is mounted by means of screw-threads upon the lower end of the pump rod section 72 for connecting the plunger 35 thereto. As is clearly shown, the plunger 35 is provided with packing 76 about the pump rod section 62 and with packing 77 bearing upon the inner face of the cylinder 33. The plunger 35 is also provided with an upwardly-opening valve 78 of any suitable type. As clearly shown in said Fig. 3, the coupling 75 provides a suitable opening from the cylinder 33 to the interior of the pump rod section 7 2, such opening being adapted to coperate with the opening through the coupling member 61 for providing free communication between the interior of the pump rod section 58 and the cylinder 33 at its upper end.

The well tube section 32 has connected to its lower end a coupling member 79 by which a suction pipe 80 is connected to the said well tube section, the suction pipe 80 being adapted to extend down in the well to a point below the suction limit of -the plungers. The coupling 79 provides a tapering seat for a valve-cage 81 supporting an upwardlyopening valve .82 of any suitable type plunger.

adapted to close the lower end of the well tube section 32. `With the plungers 39, 40 and 41 being operated successively in 120o phase relation to each other through the medium of the pump rods 26, 27 and 28, respectively, in the cylinder 30-38, and with the plungers 35, 36 and 37 being operated successively in 120o phase relation relative to each other in the cylinder 33 by the said pump rods 26, 27 and 28, respectively, in each cylinder at any given time at least one of the three plungers operating therein is moving upward at a speed approximately equal to its maximum speed of upward movement. The upward movement of any one of the plungers in the lower cylinder 33 causes the lower end of the cylinder 33 below the operative plunger to fill with water through whatever upwardly-opening valves may be located below such operative plunger, the water in the said cylinder 33 above such plunger being forced through the couplings and 6l into and through the tubular pump rod 58, being forced through such upwardly-opening valves as may be located in the cylinder 33 above such operative The water so forced upward through the tubular pump rod section 58 emerges from the upper end of the tubular pump rod section 50 into the large tubular pump rod section 115, passing upward from there into the combination pump rod section and cylinder 38 above the plunger 41, passing from that point into the well tube 25 for passage to the surface of the ground. At the same time another quantity of water is passing upward through the well tube section 32 through the registering openings in the coupling 31 and the closure member 34 into the cylinder 30-38, being drawn upward by the one of the three plungers moving upward in the cylinder 30 33 at the greatest speed at that particular time. At the same time the water above such operative plunger in the cylinder 30-38 is forced upward through such cylinder, mingling with the mass of water forced upward by the plungers in the lower cylinder in the upper end of t-he cylinder 38 above the tubular pump rod section 45. As will be readily understood, as the water is forced upward through the cylinder 30-38 by one of the three plungers operating therein, such water passes freely through the upwardly-opening valves of the other two plungers.

As will be readily understood, by the use of the mechanism described, two separate quantities of water are forced upward into the well tube 25, one quantity of water being acted upon by one set of plungers and the other quantity of water being acted upon by another set of plungers, both sets of plungers being operated by a single set of pump rods, this being accomplished by the use of two cylinders which haveaseparate and distinct inlets and which operate independently of. each other as they are actuated by the single set of pump rods.

The means shown in Fig. la for reciprocating the pump-rods 26, 27 and 2S in timed relation to each other comprises a shaft 83 provided with eccentrics 84, 85 and 86, respectively, which are connected with the several pump-rods by means of pivoted links 87, 33 and 89, respectively. The shaft 83, when rotated by power from any suitable source, serves to reciprocate the pumprods in 120 phase relation, by reasonof the equal spacing of the eceentrics about the shaft, as will be readily understood.
